Cleansing of the atmosphere in the athens area by means of rainfall and wind

In this paper we attempt to describe, using direct solar radiation measurements, the ability of the atmosphere to cleanse itself by means of rainfall and wind in the major area of Athens, which is notable for its ground relief and increasing pollution. Our results may be summarized as follows: rainfall in amounts greater than 5.0 mm, with a mean intensity of more than 2.0 mm/h has a significant cleansing effect on the atmosphere lasting for about one day. On the other hand, ground relief and the distribution of sources of pollution in the area under study do not always contribute to atmospheric cleansing.

Power grid balancing of energy systems with high renewable energy penetration by demand response

It is generally accepted that the integration of intermittent energy resources like wind energy and photovoltaics into an electricity system cannot exceed a limit of around 20% or 25%, see, e.g. [EWEA, 2005. Large-scale integration of wind energy in the European power supply: analysis, issues and recommendations. The European Wind Energy Association]. However, the decoupling of electricity generation and consumption cannot be implemented only by use of electricity storage. In the end, electricity is converted into many different energy services – quite often into thermal energy – which is better suited for storage. This article presents the results of investigations which studied the potential of those demand response activities for Germany. The investigations are based on both modelling of thermal storage devices and laboratory tests.

The practicality of distributed PV-battery systems to reduce household grid reliance

The advent of low-cost solar photovoltaics (PV) and battery electricity storage has the potential to bring about fundamental shifts in the structure of the power sector in the United States. We analyze how PV-battery systems of various sizes could reduce the dependence of residential customers on the central grid and their impact on CO₂ emissions. We further analyze how the costs of such systems change as customers attempt to decrease their dependence on the grid, considering the installed cost of PV-battery systems and the cost of electricity under a net-energy metered rate structure. We analyze these relationships for residential customers in five locations across the U.S. We find that fully disconnecting from the grid with a PV-battery system is impractical for most residential customers without also having dispatchable backup generation. Finally, we estimate how the economics of behind-the-meter PV-battery systems may change if the costs of PV systems continue to fall.

采用水上深基坑围护法建造特大型船坞坞口的创新设计

中船长兴造船基地1～4号船坞是国内规模最大的船坞工程,其中的1、2号坞由于受诸多因素的影响,总体上未采用常规的大围堰包围干施工方案,而是创造性地先利用二个独立的水上深基坑围护建造坞口,后用坞门挡水干施工坞室结构。本文简要介绍了在长江口这样一个自然条件比较恶劣的水域,利用钢板桩进行水上深基坑围护建造特大型船坞坞口的设计方案,并对本工程区别于常规陆上深基坑工程的特点及难点进行了详细的分析,以期为类似的船坞工程和水上基坑围护工程提供借鉴和参考,并对正在进行的工程施工起一定的指导作用。

利用气质联用技术对木材进行分类和鉴别

采用气质联用技术(GC-MS)对不同类及不同产地的同类木材进行分析,结果发现:不同类木材的总离子流图差别非常明显,相关系数非常小;而同类木材总离子流图基本相同,相关系数较高,并且都含有相同的特征峰.上述实验结果表明,鉴别木材有2种有效方法:一是利用相关系数,即相关系数大于0.900的可认为是同类木材;二是根据特征成分,即每种木材在其总离子流图中都有一组特征峰.     

Foundation underpinning by means of piles

Conclusions Jacked piles are more economical than bored—injection piles both in labor and material costs. Unlike bored—injection piles, they are installed with prestressing. It is advisable to place the jacked plies at distances of 5 m from each other, and to use reinforced concrete for the wall beams.

Probing ahead of TBMs by geophysical means

The potential of geophysical probing methods in TBM tunnelling is discussed. Modern TBMs have made it possible to tunnel through a wide range of geological conditions. However, the development towards more complicated machines has raised prices and often causes delays before the machines can begin operating properly. If a reliable system were available, the machine could be given a simpler design and the tunnelling process could be continuously adjusted to the prevailing ground conditions without jeopardizing safety. Geophysical investigation methods such as seismics and radar now offer the possibility of monitoring ground conditions ahead of the tunnel face. An analysis of a number of TBM projects has shown that if certain requirements on the range and time of the investigations are fulfilled, probing can be integrated into the tunnelling cycle.
